My invention relates to dough-dividing and working machines, and more particularly to machinesiin which the dough is first compressed, then divided and then '5 worked. in Jthe cells of a divider, being shaped to 'form round units by relative displacement of the cells and a dough-sup-l porting plate.

- A machine of this generaltype has been described `in .my `co-pending application Serial No. 167,500, andthe present invention relates more particularly 1to the means for yhandling the presser Y head which contains/the presser .plateandgthe divider,'with the. cells between the dividing lmives.- Preferably., the presser head is pivotally supported on the frame of the machine so as to` be lowered onto thedough supporting late aftery the.. dough to be treated hasv een the plateforl removing thegfinished balls .of dough.: .The presser-:bread` is` rather heavy and must be'handled during each operation ofthe machine, v,that-is many times every day. I Ir. order to-.aci'litate this, the presser head ispreferablybalanced'by weights, and it is yan` object offmy-invention to so arrange the weights-1 that the spacerequired for the machine;V and particularlyfthe Hoor space, is-not u increased. byy theaweights. This is important as in:bakeriesfftheffloor as arulevery restrictedmj s It is :another -."obj-ectofy myiinvention to 35, `thepresser head;l

the pree'r head and on athe frame, 5 4 are` beve gearin 36'an 37, a clutch 35, and a shaft 17` w 'ch is supported in bearings below the dough supporting-plate 18 and can be'operatievly connected. with the bevel gear 37 by the clutch 35. 17 are bevel A gears on the shaft 17 which mesh with bevel gears 41 on short shafts 41 supported in bearin of the frame below the late 18, an 42 are crank pins on each shat 41 enga g bosses 18' on the lowerl face of the ate18. j A f The parts. above described are substantially the same as in the machine forming the subject matter of'my co-pending appli-A cation aforesaid, but in the new machine means are provided `in connection with the handle 4 for controlling the clutch 35. The part 39 (Fi 2) is a'projection on the cross ead 6, an 40, 42 isl a bell crank lever ulcrumed at 71 in the frame 30 and adapted to be engaged by the projection 39 at one end and to engage the movable'sleeve of the clutch with the other end. uYVhen the handle 4 has been returned to its initial position, after the p 'operation has been completed,A and is turned a little farther to the leftin Fig. 1, the projection 39 engages below the end of the lever 40 and the clutch, 35 is thrown in so that rotation is imparted to the dough-supporting plate 18. When 'the handle 4 is released, the

clutch is thrown out by the weight of the lever 40 or b a spring (not shown).-

20 are brac ets projecting from the presser head 19 at'its rear, that is, the side opposite the-handle 4, 21 are eyes at the ends of suitable brackets 30' 'of the Yframe 30, 21 is a shaft which Acin'inects the brackets on toothed sectors on the shaft 22, 55 are'spur which are .free 'to turn on the driving .shaft 17, 50,50 are arms secured to'the spur gear 55, v49'is a balance weight' on each arniLand 48 are setscrews for varying the glsiton of tht; vivleight's llm gier 50.

e everageo t ewei ts wit respect .to the hingedl shaft and `:the pr head 19 is considerable so that the weights 49 can be small and, by bendin their arms 50 from the rear toward the' ont of the machine the balancin arts are ari-an ed within tlie iioor area o t e machine so t at no additional ground floor area is required for the weights.

' The rser head 19 is readily raised by its han e 28, being balanced by the weights '--meaeas 49, but it is preferable to effect the han lof the presser head bywer-impelle means and such means wil now be de- Referring to Fi 4, each spur gear is provided with a c utch a clutch Vpart 57 which is. fitte to slide on the shaft 17 can be connected with the corres nding part 56 through the medium of a ndle 58 which is pivoted to the frame 30.4 Theclutch parts 57 are provided with the usual annular grooves, as shown in Fig. 4, in which engage forks orl yokes 61 secured to a shift bar 62 extending at right angles to the hand llever -58 and pivoted to saidlever at 63 at some distance from the pivot 64, by which the lever is ivoted to the frame. It will be understoo by those skilled in the art that one of the okes 61 is pivoted to the frame of the mac 'ne intermediate the clutch parts and the shift bar, and is also pivotally securedto said shift bar (not shown), or is otherwise arranged in any suitable way so that one yoke moves in an op ite direction with respect to the other yo e. Thus, by operation of the hand art '56 and lever, the clutch parts 57i'will be moved axially alon the shafttoengage or disengage the c utch parts.v The shaft 17 \ro tates at all times iii the same direction and servesonly for raising the presser head,

the head being4 lowered manually or by.

presser head 19 h Afina position. I may for instance rovide projections 54 Aat each sector 54 which can engage lugs 58 connected with the handle ,58 so. as to 'displace axially and to throw out the two parte 57, as `shown in Fig. 4.

It will be `understood that the direction in which .the pr head 19 is rocked about the shaft`22, is reversedby the sectors 54 and vthe spur gears 55 so-that the weights 49 move vin opposite direction to that in which the presser head 19 is moving. In this manner it is possible t9, arrange the weights 49 and the 'presser head 19 on the ies 'saine side of the shaft22, not on opposite l sides, 'so that the wei hts do., not vproject,

from the 4fmachine, -v w ch wwould require-f 'more oo'r space.
